Re: JDBC performance issues after moving to Java 8

Mark,

Saw this is a prior post from Tim...

 Here is a tool we ship with the OS, part of the ARE product.

   From your 5250

   Enter QSH

   Then  -  /QIBM/ProdData/OS/OSGi/templates/bin/areVerify.sh -network

   ***Review the report that is generated.  If you have DNS issues it will
   tell you.
